I have a 2006 Cooper S and i let my friend who owns a 2003 Cooper S drive it, he said that he can feel that my supercharger comes on, on its own whereas his doesn't. I dont exactly understand the problem but I need to know if my friend can change his 2003 supercharger for a new one, how much it'll cost etc, etc.
Thanx Everyone!!

 

Not a supercharger problem for you.

I'm willing to bet he is feeling the difference in the newer transmission gearing. It gives the 06 MCS better pulling power in the lower rpms compared to an 03.

 

THat plus he should look into adjusting the BPV.

 

If he has the JCW upgrade kit on, he's probably referring to the flap opening up at 4500 and hence the screaming and perhaps doesn't know about it.

 

well he doesn't have the john cooper works package and he said something about my 2006 MCS's supercharger just coming on whereas his didn't. Who knows it might be the flap opening up.

 

First, please get you sig a little closer to the site gudielines, so we can all read your responses easily.

Second, earlier model Supercharger By Pass Valves have been known to need some tweaking for better preformance, so adjusting the BPV screw and/or a VGS mod and he will feel the effects of the SC much sooner. If you do a search for BPV you will find a good deal on methods for adjust the BPV also I know at least DT makes an aftermarket BPV, or he could even swap it out with a newer model BPV (don't know about fittment but the look the same I think it was just internals adjusted). The SC isn't at fault just the unit controlling when it is on.

 

MINIDEQUEENS, winner of the largest sig EVER!!!!!!!!!!!

 

lol i dont know how to get it smaller, any ideas?

 

Have photoshop? Image size>height = 300 pixels

 

Sig

 

Can a mod correct this huge sig?

Thanks

 

THREAD HIJACK: Where can I find the specs on the MCS gearing change? I'd be especially interested to find out if the top speed in 2nd gear changed at all. In fact, where can I find all the specs on a 2006 MCS (weight, wheel base, track, height, tire sizes, etc....)

 

Check the owner's manual and miniusa.com

Thank to Motoringfile for the Owner's manual link.
Link to Owner's lounge where the Owner's manual resides.

 

Holy Cr@p!!!!

That is the biggest SIG I've ever seen

 

:impatient i dont know where to look its so big

 

I suggest then that you just remove it (the sig) its very difficult to read this post.

 

mdsbrain: Thanks! Exactly what I needed!

MINIDEQUEENS: Here's your photo at a reduced size so you can fix your signature.

*laughs now about the size of the sig but then gets back to the topic...*

My friend said the same thing about his 03 MCS compared to my 06. I think it is just the gearbox that makes the difference.

Also, I tried to search for it but haven't found anything: is it normal to not hear the supercharger during the breakin period? I test drove another car and my MA drove it at first (since I'm not pro with manual yet!) and you could hear the super charger when he was shifting gears. But I asked him to drive mine around the block with me in the passenger seat (thinking that me being new to driving standard, I was just to granny-ish to push the car to hear the SC...) nope. No supercharger sound. Should I be worried?

 

Did he take you around in a JCW? The supercharger is more pronounced with the JCW airbox.

Just put a pully and CAI/HAI/AGS on... then you'll REALLY hear the supercharger.

Before I had my Helix CAI put on, I sometimes struggled to hear the SC on my stock MINI. They did a good job of deadening a lot of the whine with the stock airbox. If your supercharger wasn't working, you'd know it because you wouldn't have much pickup and go at all!

((my apologies for having to side scroll to read this... thanks to the RIDICULOUS SIG PIC!!! apparently NAM has a new feature, "Save Desktop to Signature"... good lord.))

 

I just fixed it with the image TheWrks made.

 

YAY!!!

 

Gearing is the main difference for the response... also the 05+ supercharger has the coated vanes that are good for a bit more boost...
He can always buy a new SC on ebay. I recently bought a spare/project SC that was a new take off from an 05.

 

Sweet



Back on topic Supercharger Problem

 

If he's not getting boost, and you aren't hearing lots of grinding of parts, then the SC is spinning and the boost is being lost elsewhere. If the BPV isn't closing at all, you'll have a dog of a car.

FWIW, the SOUND of the SC isn't the key it's doing what it should be, it's the MANIFOLD PRESSURE! So use something that can check for boost. This could be a vacuum/boost guage, or some sort of OBD-II data logger.

I don't think you all are using the correct diagnostics to check for what you want to measure....

I think we also have two seprate complaints, one person can't hear it as much as in a test model (mind you it will be quieter with the lower RPM it just isn't spinning as fast as a broken in car) and the other can't feel the SC kick in. I'm still think the original poster has a BPV issue on the 03, combine with a tad of the gearing change.

But like you said, if one really wants to know get some hard data (the OBD would be good to check b/w cars).
